Applications
This cutting insert is geared towards the contour-related turning of stainless steel, especially when fine surface finishes are required. The design is excellently suited for turning tasks with a continuous cutting path, where clean chip evacuation and constant dimensional accuracy are crucial.
Special features
One of the decisive purchasing features is the resilient PVD coating RT305, which effectively reduces wear during finishing. In addition, the targeted FE geometry promotes good chip control at shallow depths of cut, noticeably improving process reliability when turning stainless steel workpieces.
